Patent number: 11092708Abstract: This disclosure describes processes and systems for generating a seismic image of a subterranean formation from recorded seismic data gathers obtained in a marine seismic survey of the subterranean formation. The seismic data comprises recorded pressure and vertical velocity wavefields that are used to separate the recorded pressure wavefield into upgoing and downgoing pressure wavefields. A seismic image is computed from the subterranean formation based on a product of the downgoing pressure wavefield and a migration operator applied to the upgoing pressure wavefield. The downgoing pressure wavefield is a boundary source wavefield and the upgoing pressure wavefield is boundary receiver wavefield of the migration operator. The seismic image is iteratively updated by computing a residual seismic image based on the upgoing pressure wavefield and adding the residual seismic image to the seismic image.Type: GrantFiled: September 21, 2018Date of Patent: August 17, 2021Assignee: PGS Geophysical ASInventors: Shaoping Lu, Faqi Liu, Alejandro A.

Patent number: 10393901Abstract: Methods and systems of generating seismic images from primaries and multiples are described. Methods separate pressure data into up-going pressure data and down-going pressure data from pressure data and vertical velocity data. Irregularly spaced receiver coordinates of the down-going and up-going pressure data are regularized to grid points of a migration grid and interpolation is used to fill in down-going and up-going pressure data at grid points of the migration grid. A seismic image is calculated at grid points of the migration grid based on the interpolated and regularized down-going pressure data and the interpolated and regularized up-going pressure data. The seismic images are high-resolution, have lower signal-to-noise ratio than seismic images generated by other methods, and have reduced acquisition artifacts and crosstalk effects.Type: GrantFiled: August 16, 2016Date of Patent: August 27, 2019Assignee: PGS Geophysical ASInventors: Shaoping Lu, Norman Daniel Whitmore, Jr., Alejandro Antonio Valenciano Mavilio, Nizar Chemingui

Construction and application of angle gathers from three-dimensional imaging of multiples wavefields
Patent number: 9651695Abstract: One embodiment relates to a technological process for identifying a potential subsurface structure below a body of water. Three-dimensional seismic sensor data that includes at least two measured components is obtained. Up-going and down-going wavefields comprising multiples wavefields are constructed from the three-dimensional seismic sensor data by applying wavefield separation. The up-going and down-going wavefields are extrapolated to a reflector surface below a water bottom. An imaging condition is applied at the reflector surface to generate images that include information from the multiples wavefields. Angle gathers are constructed, where each angle gather is constructed by gathering the images generated using the multiples wavefields for a range of illumination angles. Other embodiments, aspects and features are also disclosed.Type: GrantFiled: July 22, 2014Date of Patent: May 16, 2017Assignee: PGS Geophysical ASInventors: Shaoping Lu, Norman Daniel Whitmore, Jr., Alejandro Antonio Valenciano Mavilio, Nizar Chemingui, Andrew Long, Grunde Rønholt
